Kingdom corporation (hereinafter called the "Subadviser").

         WHEREAS, Ivy Fund (the "Trust") is a Massachusetts business trust
organized with one or more series of shares, and is registered as an investment
company under the Investment Company Act of 1940, as amended (the "1940 Act");

         WHEREAS, the Manager has entered into a Master Business Management and
Investment Advisory Agreement dated May 29, 2001, as amended (the "Advisory
Agreement"), with the Trust, pursuant to which the Manager acts as investment
adviser to a specified portion of the portfolio assets of certain series of the
Trust listed on Schedule A hereto, as amended from time to time (each a "Fund"
and, collectively, the "Funds");

         WHEREAS, the Manager desires to utilize the services of the Subadviser
as investment subadviser with respect to certain portfolio assets of each Fund;
and

         WHEREAS, the Subadviser is willing to perform such services on the
terms and conditions hereinafter set forth;

         NOW, THEREFORE, in consideration of the mutual agreements herein
contained, the parties hereto agree as follows:

         1.       Duties of the Subadviser. The Subadviser will serve the
Manager as investment subadviser with respect to certain portfolio assets of
each Fund, as set forth on the attached Schedule A.

                  (a)      As investment subadviser to the Funds, the
Subadviser is hereby authorized and directed and hereby agrees, in accordance
with the Subadviser's best judgment and subject to the stated investment
objectives, policies and restrictions of the Funds as set forth in the current
prospectuses and statements of additional information of the Trust (including
amendments) and in accordance with the Trust's Declaration of Trust, as
amended, and By-laws governing the offering of its shares (collectively, the
"Trust Documents"), the 1940 Act and the provisions of the Internal Revenue
Code of 1986, as amended (the "Internal Revenue Code"), relating to regulated

be adopted by the Trust's Board of Trustees, and provided that the Trust
Documents are all furnished to the Subadviser, to develop, recommend and
implement such investment program and strategy for the Funds as may from time
to time be most appropriate to the achievement of the investment objectives of

analysis relative to the investment program and investments of the Funds, to
determine what securities should be purchased and sold and to monitor on a
continuing basis the performance of the portfolio securities of the Funds.

                  (b)      The Subadviser shall (i) comply with all reasonable
requests of the Trust for information, including information required in
connection with the Trust's filings with the Securities and Exchange Commission
(the "SEC") and state securities commissions, and (ii) provide such other
services as the Subadviser shall from time to time determine to be necessary or
useful to the administration of the Funds.

                  (c)      The Subadviser shall furnish to the Trust's Board of
Trustees periodic reports on the investment performance of each Fund and on the
performance of its obligations under this Agreement and shall supply such
additional reports and information as the Trust's officers or Board of Trustees
shall reasonably request.

                  (d)      On occasions when the Subadviser deems the purchase
or sale of a security to be in the best interest of a Fund as well as other
customers, the Subadviser, to the extent permitted by applicable law, may
aggregate the securities to be so sold or purchased in order to obtain the best
execution or lower brokerage commissions, if any. The Subadviser also may
purchase or sell a particular security for one or more customers in different
amounts. On either occasion, and to the extent permitted by applicable law and
regulations, allocation of the securities so purchased or sold, as well as the
expenses incurred in the transaction, will be made by the Subadviser in the
manner it considers to be the most equitable and consistent with its fiduciary
obligations to the Fund involved and to such other customers. In no instance,
however, will a Fund's assets be purchased from or sold to the Manager, the
Subadviser, the Trust's principal underwriter, or any affiliated person of
either the Trust, the Manager, the Subadviser or the principal underwriter,
acting as principal in the transaction, except to the extent permitted by the
SEC and the 1940 Act.

                  (e)      The Subadviser shall provide the Funds' custodian on
each business day with information relating to all transactions concerning each
Fund's assets and shall provide the Manager with such information upon request
of the Manager.

                  (f)      The investment advisory services provided by the
Subadviser under this Agreement are not to be deemed exclusive and the
Subadviser shall be free to render similar services to others, as long as such
services do not impair the services rendered to the Manager or the Trust.

                  (g)      The Subadviser shall promptly notify the Manager of
any financial condition that is likely to impair the Subadviser's ability to
fulfill its commitment under this Agreement.

                  (h)      The Subadviser shall review all proxy solicitation
materials and be responsible for voting and handling all proxies in relation to
the securities held in a Fund's portfolio. The Manager shall instruct the
custodian and other parties providing services to the Fund to promptly forward
misdirected proxies to the Subadviser.

         2.       Delivery of Documents to the Manager. The Subadviser has
furnished the Manager with copies of each of the following documents:

                  (a)      The Subadviser's current Form ADV and any amendments
thereto;

                  (c)      Separate lists of persons whom the Subadviser wishes
to have authorized to give written and/or oral instructions to the custodian
and the fund accounting agent of Trust assets for the Funds; and

                  (d)      The Code of Ethics of the Subadviser as currently
in effect.

                  The Subadviser will furnish the Manager from time to time
with copies, properly certified or otherwise authenticated, of all material
amendments of or supplements to the foregoing, if any. Additionally, the
Subadvisor will provide to the Manager such other documents relating to its
services under this Agreement as the Manager may reasonably request on a
periodic basis. Such amendments or supplements as to items (a) through (d)
above will be provided within 30 days of the time such materials became
available to the Subadviser.

         3.       Expenses. The Subadviser shall pay all of its expenses
arising from the performance of its obligations under Section 1.

         4.       Compensation. The Manager shall pay to the Subadvisor for its
services hereunder, and the Subadviser agrees to accept as full compensation
therefor, a fee with respect to each Fund as set forth on Schedule B. Such fee
shall be accrued daily on the basis of the value of the portion of the average
daily net assets of the applicable Fund as are then being managed by the
Subadviser and shall be payable monthly. If the Subadviser shall serve hereunder
for less than the whole of any month, the fee hereunder shall be prorated
accordingly

         5.       Purchase and Sale of Securities. The Subadviser will
determine the securities to be purchased or sold with respect to the portion of
each Fund's portfolio assets being managed by it, and shall purchase securities
from or through and sell securities to or through such persons, brokers or
dealers as the Subadviser shall deem appropriate in order to carry out the
policy with respect to allocation of portfolio transactions as set forth in the
prospectuses and statements of additional information (including amendments) of
the Funds or as the Trust's Board of Trustees may direct from time to time. In
providing the Funds with investment management and supervision, it is
recognized that the Subadviser will seek the most favorable price and
execution, and, consistent with such policy, may give consideration to the
research services furnished by brokers or dealers to the Subadviser for its use
and to such other considerations as the Trust's Board of Trustees may direct or
authorize from time to time.

                  Nothing in this Agreement shall be implied to prevent (i) the
Manager from engaging other subadvisers to provide investment advice and other
services in relation to series of the Trust, or a portion of the portfolio
assets of any such series, for which the Subadviser does not provide such
services, or to prevent the Manager from providing such services itself in
relation to such series; or (ii) the Subadviser from providing investment
advice and other services to other funds or clients.

                  In the performance of its duties hereunder, the Subadviser
is and shall be an independent contractor and except as expressly provided
herein or otherwise authorized in writing, shall have no authority to act for
or represent the Trust, the Funds, any other series of the


                                      -3-


<PAGE>


Trust or the Manager in any way or otherwise be deemed to be an agent of the
Trust, the Funds, any other series of the Trust or the Manager.

         6.       Term of Agreement. This Agreement shall become effective as
of the date first written above or such later date as the shareholders may

have notified the Manager in writing at least 60 days prior to such September
30 or prior to September 30 of any year thereafter that it does not desire such
continuance. This Agreement may be terminated at any time, without payment of
penalty by a Fund, by vote of the Trust's Board of Trustees or a majority of
the outstanding voting securities of the applicable Fund (as defined by the
1940 Act), or by the Manager or by the Subadviser upon 60 days' written notice.

defined by the 1940 Act) or upon the termination of the Advisory Agreement or
if (a) either party is unable to pay its debts or an administrative or
insolvency order is made in respect of a party pursuant to its relevant
governing and applicable laws and regulations or (b) a party commits a material
breach of any of the terms or conditions of this Agreement and such breach
shall continue 30 days after notice in writing, specifying the breach and
requiring the same to be remedied, has been given.

         7.       Amendments. This Agreement may be amended by consent of the
parties hereto provided that the consent of the applicable Fund is obtained in
accordance with the requirements of the 1940 Act.

         8.       Confidential Treatment. It is understood that any information
or recommendation supplied by the Subadviser in connection with the performance

Subadviser, expressly for use in the Trust's Registration Statement or other
than upon verbal information confirmed by the Subadviser in writing expressly
for use in the Trust's Registration Statement; provided, however, that in no
